XML load error. Absurd!

[Zpixel]

The RSS link http://fun.1zarb.ir/rss looks standard but php gives error on load:

DOMDocument::load() [domdocument.load]: Space required after the Public Identifier in http://fun.1zarb.ir/rss, line: 1

DOMDocument::load() [domdocument.load]: SystemLiteral " or ' expected in http://fun.1zarb.ir/rss, line: 1

DOMDocument::load() [domdocument.load]: SYSTEM or PUBLIC, the URI is missing in http://fun.1zarb.ir/rss

and this is the code:

$doc  = new DOMDocument();
$doc->load($url);

most feeds were loaded without any trouble. what's the solution?
thanks.

I get no such error (PHP version 5.2.6, Apache 2.2.8, Windows Vista).

<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);

$url = "http://fun.1zarb.ir/rss";
$doc = new DOMDocument();
$doc->load($url);
